' Disk wheels consisting of twmmnamm whic'htou ch each 'o't-l 'at the 'vaulted sides and are fastened in thecent'er by a spl t boss,

are. well. known. The disks. of these wheels" cannot be made out of thin sheetiron, for. 7 experiments have shown that the wheels then can easily'betwisted by working pressures.

independent of the working pressures'if This invention avoids the disadvantages'of such disk wheels and makes it possible to build them" of" thin sheet" iron. The disk wheels consist of two iron disks which touch each other at the vaulted sides and are fastened in the center by a split boss; the flanges of the boss are sloped from wlthout to within nearly to the center of the inside; Their cross-section forms a female cone which takes up the conical edges of the disks. These edges are directly'fixed upon the outside edges of the boss flange by means of rivets, screws, etc., in order to prevent the edges "of the disks from twisting. The rivets or screws, etc., in the disks support each other inside between the flanges of the boss.

A special construction of. this disk wheel is shown in front view Figurel of the drawing and in an axial cross-section in Figure 2.

The body of the wheel consists of two circular thin disks of sheet iron, each of which tially to the conical part a these bosses has a'fiat circular bottom a in thecenter, a conical part a and a fiat edge a In the hollow part of eachdisk there is a boss in the form of a plate b 6 which fits exactly to the fiat bottom a and parhave a collar?) for better bearing in the axle bushes.

Each disk is supported against the boss by an annular seat 6 within the seat there is the annular space 6 x Disks and bosses have their conical parts a 5 fixed together by rivets or screws 0;

the rivet heads of the interior parts. are

rubbed clowintouching each other exactly, when the disks are connected together.

The disks will be connected by five screws (Z, which fix at the same time the body of the wheel to the axle bush. a

t is important that these screws cl pass through the conical parts (1?, b of the disks and bosses; only in this way is it possible to avoid twisting even of very thin sheets.

This kind of fastening however is only pressed to the base rim'e.

reliable 'in servicedivhen thedisksandithe base of rim are rigidly fixedtogether'; only in this case are'the fdisks exclusively stressed v f co For th s purposethe base rim has on, each v side ELCIICHlaI flanges? fixed in radialdi- I Inspitefof its vaultedform the disk will 6 beelast'ic;'ja' strong pressure on the bottom a directed against the'fiangee pr'esses the and e t'o ge l er throughout their 67 tire extent" and equally againstthe base Under such a compression the edge a of the disk will be riveted round about with the flange e of the base rim 6 or better fastened by electrical welding.

As soon as the pressure against the bottom I a of the disk decreases, the disk endeavors to return to its former shape; but itwill be prev nted from doing so by the rivets or', the welded joining. Therefore, the edge of Y r the disk remainsv always fastened and com- Inthe same manner both the disks; are

their bottom a as wellas the rivets 0 are compressed together when. readyfor use;

therefore both the disks when in use are H firmly supportedby the base rim, even in taking curves the disks are only stressed by compression.

The connections, for example the rivets 5 in the flanges a and the edges a will never be stressed by working pressures; even in joined withthe corresponding flanges and operation they can only-be stressed by the i forces with which the elastic disk endeavors to regain its former shape. a

The disk wheel with its thin disks ing to the present invention ness of a cast steel wheel.

."It'is possible to fasten the disks to the base I'lIIl by calkingwholly or partially the.

edges a of the disks withv the edges e or by .soldering. j

. At'all events it will benecessary that the flanges e are fixedto the base'rim and-that the disks with their edges a are fastened accordhas the toughto the inside of the fianges'e only in this case can the disks be perfectly supported.

Therefore the base rim 6 must be divisible at one place in order to give way when the disks will be introduced.

' Theannular space 6 between the-bosses is the opening for the key which separates the bosses anddisks from each other and o makes it possible to dismount the base rim;

even in this case it is not necessary to touch and means for securing said portions of the v disks to the splayed part of the boss.

2. A'disk Wheel comprising disks converging from the Wheel rim tot-he center thereof with the portions of the disk at the center of the wheel in contact with each other, a boss having an internal seat for-the contacting' parts of the disks and a splayed periphery. engaging the converging parts of the disks adjacent the said seat andrmeans for connecting the splayed parts of the boss with the adjacent parts of the disks.

3. A disk Wheel comprising sheet metal disks converging from thewhe'el rim to the center-thereof, a boss into which the inner ends of the disks extend, said boss having a splayed periphery, outer portions of the converging disks engaging the inner faces of thesplayedperiphery of the boss, and

means for connecting the disks to the boss.

7 4. A disk wheeivcomprising disks converging from the Wheel rim to the center thereof, aboss havin a spiayed periphery with the inner face 0 which outer portions of the disks engage, and means supporting each other between the splayed. portion of the boss for connecting the disks to the boss.
